Sorry, I haven't been keeping up with the post.
I have put side skirts and rear fender skirts on. I made a small belly pan from the front bumper to the oil pan. Blocked some of the gaps around the radiator.
changed the oil to 0W20
No AC unit on top
1990 LeSabre 3800 FWD transverse power train fits, fire wall was modified.
Will be testing MPG soon on the highway.
TC locks up around 55 mph in OD (1400 rpm) 45 mph in D. Better to keep in in D and locked up ageist a head wind than slipping in OD.
